2. Overview of Fuse Management Central Architecture

The diagram below display and briefly describes Fuse Management Central conceptual architecture, designed for high performance, scalability and security.

fuse architecture
1 Fuse Management Central integrate with OpenText ™ Directory Services to manage and authenticate its users.
OpenText ™ Directory Services provides a scalable identity management solution, by integrating multiple authentication services, such as Active Directory or Google.
2 Fuse Management Central is the secret sauce central piece, responsible for orchestrating all system monitoring and management activities, regardless of its cluster type, whether productive or non-productive.
3 Fuse Management Central Database stores all application related data, such as administration settings, access roles.
4 Fuse Management Central Metrics Database is used for long term metric storage, allowing system administrators to perform a temporal search on system metrics, combining them on aggregated system metric snapshots over time.
5 Fuse Management Central Alert Manager takes care of interpreting, deduplicating, grouping, and routing alerts to Fuse Management Central while allowing the option of silencing and inhibition of alerts.
6 All managed systems require Fuse Management Client installed and activated. Fuse Management Client is responsible not only for collecting and dispatching all system components metric data but also to make the system management interface available while ensuring the data interchange security.

  1. Stop all Fuse Management Central services.

  2. Using the Windows application for removing programs (for example, Programs and Features), select Fuse Management Central installer and then click Uninstall.

  3. Use the uninstall wizard automatically to remove all Fuse Management Central installed components.

7. Appendix A - Troubleshooting

7.1. Known Issues and Workarounds

This section describes scenarios that users may run into and how to troubleshoot and workaround or fix them.

7.1.1. Fuse Metrics Database corrupted files

Sometimes some data files in Fuse Metrics Database can get corrupted, preventing the Metrics service to start. We found that this commonly happens in these scenarios:

  • Fuse Metrics Database service was not shutdown correctly

  • Disk ran out of space

If this happens we suggest to shutdown Fuse Management Central (all services) and then restart Fuse Management Central (all services).

At this point some errors may appear when restarting Fuse Metrics Database, in case there are corrupted data files. If an error appears when starting Fuse Metrics Database, please check the Fuse Metrics Database logs. Errors like these should be being logged:

err="opening storage failed: block dir: \"data\\\\01E270EBZ1YPKF7BB2WZ38H5SV\": open data\\01E270EBZ1YPKF7BB2WZ38H5SV\\meta.json: The system cannot find the file specified."

or

err="opening storage failed: found unsequential head chunk files 23 and 25"

In order to fix this, the folder or file specified in the log message, for example 01E270EBZ1YPKF7BB2WZ38H5SV or chunk files 23 and 25, should be deleted. These folders can be found in the Fuse Metrics Database installation folder, inside the data or data/chunks_head folders.

This process should be repeated for each folder or file that appears on the logs until Fuse Metrics Database is able to start with no errors.

7.1.2. Uninstall Fuse Management Client for OpenText Content Server (16.2.2, 16.2.3, 16.2.4)

For the Content Server versions 16.2.2, 16.2.3 and 16.2.4, we found out that the standard soft-restart is not enough to reload all the loaders required for Fuse Management Client, so we suggest you to restart the processes/services of Content Server to make sure everything was updated.
